In a 8-2 ruling, Mexico’s Supreme Court ruled Mexico City’s six-month-old same-sex marriage law, passed in December, is just fine, as it doesn’t violate the Constitution. In fact, the Constitution offers no definition for “family,” so state prosecutors alleging it will harm the family don’t have any ground to stand on. That means the hundreds of couple who began marrying in March can keep their certificates. Update: In a 9-2 ruling, the court also said all Mexican states must recognize the capital’s gay marriages.
